Minimum energy consumption, maximum performance. The Hydor Centrifugal Pump miniature water pump extends range of use while keeping power consumption low. Flow control knob allows water output to be adjusted to your specific aquarium needs. Unique pump design allows efficient operation even in low aquarium water level conditions. Ideal for tight aquarium spaces and for use in terrariums or table fountains. The high performance Centrifugal Pump is also perfect as a petite powerhead for enhancing water movement in compact nano aquariums. Safe for use in freshwater and saltwater aquariums.

Installation
Please verify that all components of the pump are undamaged before putting it into function. Do not operate the pump completely out of water. Running the pump dry will cause structural damage to the rotor.

Maintenance
Note: Regular cleaning and maintenance of the pump will guarantee better performance and durability. Before any kind of intervention, always disconnect the pump and any other submerged equipment from the electrical supply.

Detach the rotor chamber/flow control component from the pump body and then remove the rotor.

Clean the rotor and well with a soft brush.

Rinse thoroughly with lukewarm water and reassemble components.

Do not use solvents or detergents of any kind.

Note: Although the unique construction of Hydor Pico Evolution Mini Pump Models 200 and 400 allows the operation in very low water levels, operation is not recommended at a water level lower than 1.5 centimeters. The pump can operate both in a vertical or horizontal position. The water flow can be directed by turning the rotor chamber regardless of the pump's position.

When choosing a water pump type and size, there are several factors to include in your decision. Filtration type, desired flow rate, plumbing and head height, and adding additional devices all come into play. This article helps clear the confusion.

Your primary objective is to maintain a healthy thriving aquatic environment for your underwater plants and animals. To achieve this goal, one of the most critical decisions you'll make is choosing the right pump. Compare pumps here.

great little pump
this is another great pump from hydor. I use mine with a GFO reactor. Its easy to set up and adjust to get the right flow. The small size leaves more room for other things and is quiet.

Works as stated
I purchased this pump to run a small remote sand bed. I only needed about 100gph and this fit the bill perfectly. It's quiet and very efficient to run.

I'm using it in a pet fountain, not a fish tank. Pump is submerged in fountain reservoir.The pump has a 6 foot cord with a two-prong polarized safety plug that goes directly to wall AC. There is no "wall wart" transformer or miniplug connection. The power cord is well insulated and appears to be heavy duty.Hope this helps.

It has to travel from the reservoir a total distance of about 6 feet, 4 of those feet vertically as the reservoir is on the floor next to the stand and it is going to feed directly into the tank. I don't want a fast flow though, they recommend that the pump feeds in the water slowly over 5-10 minutes so I'm not totally sure how to figure that out.

Answer:

I would go with a larger pump, that way you know it has the power for a 4ft head pressure. You can always adjust the flow with a valve. The discription should have the flow info on it. When in doubt go larger.
